It’s been a while since we checked in with Christopher O’Riley, the pianist known for his majestic renditions of Radiohead and Elliott Smith songs. But now, O’Riley returns with cellist collaborator Matt Haimovitz for Shuffle.Play.Listen, an two-disc album whose second side features classical arrangements of songs by Arcade Fire, Radiohead, Cocteau Twins and Blonde Redhead. Check out their take on Arcade Fire’s “Empty Room” below.
